How NVIDIA's chip gains flow through the entire AI stack 14:44 — Space vs terrestrial data centers: can you launch a gigawatt for under $20B? 20:45 — Earth is getting scarce. Why that changes the math on space-based compute entirely 24:01 — When does space compute go from concept to reality? Brett's take Follow @wintonARK, @downingARK, @skorusARK.
